Bad smell in bath towels never again, look what an incredible tip

Additional Tips:

Use fabric softener in the washing machine, which will effectively eliminate any odor present in the bath towels, in addition to removing any residual stains. The lavender version or any floral style of this product leaves the towels soft and with a pleasant aroma.
Baking soda is an excellent alternative as is vinegar for cleaning clothes, especially bath towels. It can help neutralize odors, restore fabric colors and make them pleasantly soft.
If you have to wash your swimming or beach towels, I have a great suggestion: add 100 ml of kitchen detergent to the wash cycle. This will help remove any remaining body oil or sun lotion from the cloths.
After you shower, be sure to hang the towel to dry, but not in the bathroom itself.
Additionally, you should change the towels twice a week.
This is essential, as body oils and sweat stuck to the fabric impede air circulation and can cause towels to not dry properly.
Finally, when you wash them, use white vinegar to rinse them and do two rinse cycles to make sure all soap or fabric softener residue is gone.
